Today social media, such as Facebook has a big influence on how people interact with each other. I'm pretty sure that without Facebook I myself would have a hard time, to keep in contact with the friends I don't go to school with.
These days you can connect on all sorts of ways. When you are sitting at a restaurant maybe with a friend, you can tweet or write a status update about it on Facebook, letting everyone you know what you are doing right this moment. Not only what you are doing, but who you are doing it with and where and when.
And it's not only people that are using Twitter and Facebook, it's also firms promoting their brand and artists you can click "like" on.
But with all this social media, what is going to happen with face to face interaction? Personally I think face to face are the most vital. Sure you can get to know someone online, but it's not the same. You can't drink a cup of coffee with another person online. The most deep conversations should be face to face, you can't give comfort trough textual communication only.
Think about how bad social skills we would all have, if we only had interactions with each other online, or via text, phone or web cam!
